Genistein(NPI 031L) 是一种存在于豆制品中的植物雌激素，是一种高度特异性的蛋白酪氨酸激酶 (PTK) 抑制剂，可阻断 EGF 对 NIH-3T3 细胞介导的有丝分裂作用，IC50 为 12μM，或阻断胰岛素介导的有丝分裂作用，IC50 为 19 μM 。

Genistein(NPI 031L), a phytoestrogen found in soy products, is a highly specific inhibitor of protein tyrosine kinase (PTK) which blocks the mitogenic effect mediated by EGF on NIH-3T3 cells with IC50 of 12μM or by insulin with IC50 of 19 μM.(In Vitro):Genistein inhibits serum-stimulated growth of MCF-7 and T47D ER+ cells with IC50 values of 7.6 and 8.7 μg/mL by dye exclusion, respectively, and 8.7 and 10.6 μg/mL by [3H]thymidmne incorporation, respectively. These values are similar to the IC50 values of 9.4 and 7 μg/mL for MCF-7 and T47D ER+ cells, respectively, obtained with the MTT assay. Additionally, Genistein at concentrations up to 20 μg/mL does not alter MTT mitochondrial reduction when compared to control cells in an 8 h incubation period. Furthermore, neither biochanin A or daidzein are found to interfere with the MTT assay at IC50 concentrations. Therefore, the MTT assay is valid for determining growth inhibition by Genistein at concentrations under 20 μg/mL in the systems studied.(In Vivo):Bisphenol A (BPA) treatment alone and combined with Genistein had no significant effect on the protein expression of LC3II and PPARα in liver of STD- or HFD-fed rats (P>0.05; P>0.05). Significant decreasing of the protein expression of PPARγ in liver is observed when Genistein is added to rats, compared to either HFD group or HFD-BPA group.
